Keeva Island

chanhed few things to make the circles easier to fit:

with water bodies named:

Given that mountains are usually impassible, my guess here is that Nero and Viba are not connected.

Maybe I'm saying this too early, but the coastline should not continue through the river. The water in the river and the water in the sea are connected after all

I like the fact that you added names to the sea parts, but I don't really like the names themselves.
Usually a sea is not named after a small island inside of it, and your name is already in the bottom left together with Marcoxa's. No real need to add it to the strait there too. I would choose one of the territories to be your imaginary main port (e.g. Panive), and call it the "Strait of Panive" or something.
Also, the strait would be the water between the points of Ceju Wear and Ruben right? Not the water to the right of it. I feel if it's a strait, the letters should be more to the left.
